In Sketchup the user made a cube thats 100cm x 100cm x100cm and has Sketchup's measure units set to cm. When imported into DataSmith the cube is 39x39x39. It was calculated that the scaling was off by 2.539998628400741.

This was reported in 4.20 (4.20E3) and reproduced in 4.19.2 (0.182)

Steps to Reproduce
  1. Download the attached files
  2. Open the UE4 Editor and create a blank Unreal Studio project
  3. Navigate to the Import DataSmith button and click on it
  4. Import the .udatasmith file

Results: In Sketchup the cube is exported at 100cm x 100cm x100cm. In DataSmith it imports at 39 x 39 x 39.

Expected: The DataSmith file maintains the Sketchup dimensions when imported.

In SketchUp, changing the unit scale is done through Window > Model Info then in Units section change format ie Decimal > cm
